Title: Improvements relating to the performance of nuclear fission reactions and to apparatus therefor
IPC: G21C1/22
Filed: 1956-06-20
Abstract: 795,421. Nuclear reactors. STICHTING REACTOR CENTRUM NEDERLAND. June 20, 1956 [June 25, 1955], No. 19134/56. Drawings to Specification. Class 39(4). In a homogeneous nuclear reactor, a suspension of solid fissile material in a moderating liquid is circulated upwards through the reaction zone, with laminar flow and with an upward velocity greater than the settling rate of the fissile material to produce a uniform vertical concentration. The suspension consists of natural or enriched uranium oxide in water or heavy water. The fuel suspension enters and leaves the reaction vessel, a vertical cylinder, through guide vane systems to prevent turbulence. The inlet vanes may be inclined to give the suspension a slight rotary motion, to prevent vertical circulating currents, while the concentration to the centre is reduced. On leaving the reactor, the suspension passes through a heat exchanger and is pumped back to the inlet after the moderator decomposition products have been catalytically recombined and the dissolved fission products removed by an adsorbent. Specification 783,985 is referred to.

IPC: C21C5/04
Filed: 1918-11-21
Abstract: 128,836. Ryding, H. C., and Allen, A. W.. Nov. 21, 1918. Cast-iron processes.-Basic open-hearth steel is made from a charge of blown metal and slagforming material, e.g. lime and oxide of iron, the blown metal being added in two portions, one containing a low and the other a high percentage of carbon. The slag-forming material may be charged before the low-carbon metal, or after it and before the high-carbon metal, and these two methods of working may be employed alternately, so that the first method will effect a building- up of the furnace bed in consequence of the lime adhering to it, while the second method will result in the erosion of the bed so built up. Four parts by weight of low-carbon metal containing about 0.06 per cent of carbon and one part of high-carbon metal containing 2.5 to 3 per cent of carbon may be used.

[Also in Division H2] The motive power for a vehicle which moves over a prepared track so that it is supported by cushions of air, is derived from a linear induction motor 1 which is normally set for forward movement by means of pole-changing unit 2, the main supply 3 being derived from a generator on the vehicle or from an external source. For braking the pole-number of the motor 1 is set for a lower synchronous speed so that the main motor regenerates to energize an auxiliary linear motor 4 which produces a reverse torque. The auxiliary motor is associated with a further pole-changing unit 5. The motor 4 may also be energized from the supply 3 to augment the braking thrust. The vehicle may be decelerated in a number of stages by setting successively lower synchronous speeds for the main motor, final stoppage being effected by mechanical braking. An exciter 7 maintains the field of the motor 1 in the event of power supply failure. The unit 2 is controlled by a velocity detector 6. Pads 10 are fed with pressurized air from compressors 11, 12, driven by engines 13, 14, the pressure of air from the pads reacting on track 15 which carries armature rail 16. Stabilizing pads 17 are provided. The motors 1, 4 may be combined in a single motor. Specification 995,127 is referred to.

Abstract: 585,464. Electric currents converting. MACKAY, D. M., and WRIGHT, C. S. Nov. 26,1943, No. 19749. [Class 38 (ii)] An electric power supply unit for feeding a load during one of an even number of successive half-cycles of an A.C. supply, includes one or more time delay networks having time delays of an integral number of half-cycles, connected to the A.C. supply so that energy for feeding the load during the one half-cycle is evenly distributed throughout all of the successive half-cycles. In the embodiment shown in Fig. 1, one half S1 of the secondary winding of a supply transformer P is directly connected to rectifier R1 and load condenser K, while the other half S2 is connected to a second rectifier R2 having the same load K through a network N having a time delay of one halfcycle. Thus, both rectifiers conduct simultaneously during one half-cycle to charge condenser K to a voltage equal to that across one half-winding S1 or S2, the energy being drawn from windings S1 and S2 during successive half-cycles. In a modification, Fig. 2 (not shown), the two rectifier circuits are connected in opposite senses across the whole of the transformer secondary, and separate load condensers having a common terminal are provided. The output voltage, occurring during alternate half-cycles, is at twice the supply voltage. In Fig. 3, a single rectifier R and load K are connected across points ZX of a three-terminal network N having a delay of one half-cycle. Since the voltage across YZ is 180 degrees out of phase with the voltage across XY, the voltage across XZ is twice that across the secondary S of the supply transformer, and gives a rectified output of this value during alternate half-cycles although the energy is drawn from the supply during successive halfcycles. By combining three such networks, a voltage of four times the supply voltage and occurring during every fourth half-cycle may be obtained (Fig. 5, not shown). The rectifiers may be replaced by spark gaps.
